MACHINE FOR MAKING: CAN-BODIES.

Specification of Letters Patent.

' Patented a ri 27, 1909.

' Anvlication filed July 11, 1905. Serial No. 269,230.

To all whom it may concern: Be it known that I, JOSEPH O. DONNELLY, a citizen of the United States, and resident of Detroit, in the county of lVayne' and" State of Michigan, have invented certain new and useful Improvements in Machines for Making Can-Bodies, of which the followtus embodying my invention.

ing is a specification.

This invention relates to machines for to'rming can bodies; myobject being to providea machine whereby can bodies having a joint or seam of superior character shall be rapidly and effectively produced.

. In the present embodiment of my invention, suitable blanks of sheet metal are fed to and through appropriate devices by means of which flanges are formed along the longitudinal edges of the blanks, and thence through a former by means of which the flanged blanks are forced around traveling inandrels, Flanged joint strips are progressively formed, and fed to, and interlocked with, the flanged edges of the blanks on the mandrels, and the interlockedparts are then subjected to the impact of a hammer device during, their traverse. The c vlindrical bodies thus produced are next carried to fluxing and soldering devices by means of which the joints or seams produced by the interlocked members are effectively soldered toge her, and the can bodies thus produced are then successively discharged from their respective mandrels.

The invention comprises various novel features of construct-ion, combinations and.

organizations of parts which will be hereinafter fully set forth, and then particularly pointed out in the claims.

the line 1212 of Fig. 2. Fig. 13 is a perspective view, partly. in section, ofthe soldering device. Fig. 14 isatransverse section, enlarged, as onthe line 14-1 4 of Fig. 1, showing the action'of the first set of flanging wheels, on the edges of the blank for the can body. Figs. 15, 16, 17 and 18.are-sec-' tions illustrating each of the successive flanging wheels and the progressive action thereof upon the blank. F ig. 19 is a transverse sect-ion, enlarged, as on the line 19-19 of Fig. 1, showing the actionof the first set of flanging wheels on the edgesof the blank .for the joint-strip. Figs. 20, 21,v 22 and 23 are similar sections, showing the succeeding sets of flanging wheels and their progressive action upon the blank. Fig. 24 is a transverse section, enlarged, through the hammer devices, as on the line 24-24 of Fig. 2".

Fig. 25 is a vertical section, as on the line 25-25 of Fig. 24. Fig. 26 is a similar section, as on the line 2626 of Fig. 24.

1 indicates the main frame of suitable shape and size to support the various parts of the apparatus; and 2 the main driving shaft extending lengthwise and to one side of the main frame, andhaving a drive pulley 3 to which the motion is transmitted from a suitable source of power. V

At one end of theymain frame is a hopper 4 for the reception of superposed blanks A of sheet metal for the can bodies. In the lower rear edge of the hopper is a space 5, throu h which the lowermost blanks are successive v expelled. In the present instance the blanks are removed by means of a pair of endless chains 6. provided ati'egular intervals with j lugs 7 which during the travel. ot the chain,

In the drawings-Figure 1 and Fig. 1, 3

considered together, are a plan of an appara- Fig. 2 and Fig. 2 are a side elevation thereof. Fig. 3 and Fig. 3 are a vertical section, enlarged, as on the line 3-3 of Fig. 1. vation of the mechanism for supporting the oint strip in the path of the can body,

shop'ing adjacent parts of the machine.

Fig. 5 is a transverse section, as on the line 55 of Fig. 2. -Fig. 6 1s a similar section, as on the line 66 of Fig. 2.

Fig. 7 is a sec- 1 take against the opposing edges of the blanks. These chains are carried -by sprocket wheels 8 on suitably disposed T shafts 9. The rearward shaft 9, is provided t is an eleat one-end with a bevel gear wheel 10 which meshes with a sunilarwheel 11 on a vertical shaft 12, the latter shaft being geared with tion as on the line 7-7 of Fig. 2. Fig. 8 is f chains, are two rows of flangnig wheels 15. i The wheels of each row are carried by verti- Fig. 10 is a section as on the line 10- 10 of Fig. 2. Fig..11 is a section as on the line 11 -11 of Fig.2 Fig. 12 is a section as on the main shaft by coacting :ievel gear wheels 13, 14, respectively. Thus the sprocket chains are positively driven.

Directly in rear of the hopper, and in the paths of the respective lateral edges of each blank as it is carried therefrom by the thereon. These plates extend inward toward the median line of the machine, a space being afforded between the plates and the frame top for the passage and guidance of the'blanks. "In the resent instance there 5 are five flangingwhee sin each row, and they beveled from the base toward the axis of the wheel to impartaslight upward bend to the opposing edge of the blank; the periphery of the second wheel (1)) is parallel to its axis to turn the edge to a-vertical position; the' periphery of the third wheel (0) has a plane basal portion with an outwardly-beveled portion, to turn the edge partially inward; and the peripheries of the remaining wheels ((1 and e) are inclined or beveled outwardly at decreasing angles so as to bend the upturned edge of the blank still farther inwardly. Along the under portion of the plate, adjacent each row of wheels, is set a strip of steel 18 having a beveled edge against which the opposing ed e of the blank is turned by the wheels in or er to insure a shar and uniform bend.

T 1e two rows of Wheels correspond with each other in all particulars and hence the longitudinal edges of the blank are simul taneously andsimilarly acted upon thereby. Extending from end to e nd-of the machine, along the niiddle thereof, is a sprocket chain 19 which is supported 'upon large sprocket wheels 20 at the respective ends of the main frame. The shaft of one of the wheels is ro- 40 meshes a bevel pinion 22, on the main shaft thereby positively driving the chain. This chain carries at regular intervals cylindrical mandrels 23 around and against which the blanks are gradually and forcibly turned, and each of which mandrels is of adiameter equal to the internal diameter of the canbody to be produced, or practically so. In each of the mandrels, along that side thereof which is uppermost while the blank is being pressed thereon, is a longitudinal groove'or channel 24 which receives the upper lipped edges of the blank when the latter has circumscribed the mandrel.

The mandrels are preferably formed on or secured to outwardly-extending lugs 25 on the inner links of the chain in such position as to lie slightly aboveand parallel with the other links while the chain is in horizontal position, and the basal ends of the mandrels are provided with flanges 26. These mandrels are so disposed on the chain that as they pass upward at the forward end of the machine, they successively enterthespace 65 between the plates 17 and as they move the blank and serves as an abutment thereparts which are'bolted to the main frame.

vided with a bevel spur wheel 21 with w ich alon they pass above and thus overhang the blan which are being acted upon by the forming wheels The flanged portion of each mandrel takes against the opposing edge of for. Each of the inner links of the chain is longitudinally slotted or bifurcated to receive therein, beneath the lug 25, one arm of a lever 27, the'other arm of which extends beneath the adjacent mandrel. Confined within a socket in the lug is a spiral spring 28 which bears upon the opposing arm Off 111616. ver and, thus forces theother arm thereof yieldingly toward the mandrel. The lever thus serves as a clamp member which co-acts with the. mandrel to grip the interposed blank.

' Supported upon thev bed in rear of the flanging wheels, is a hollow forming member 29 having internal curved walls whichare parallel throughout their length to the axis of said member, the latter being, in effect the diagonal section of a longitudinally slotted cylinder. This cylinder section gradually inclines rearwardly from the bed, its internal diameter, being equal to that of the external diameter of the can-body to be formed, or practically so, and the member being referably formed of two longitudinally ivide'd When the horizontally. disposed blanks, with the lips orflanges formed thereon, leave the flanging wheels, they are carn'edrearward into and through the forming member 29, by their respective mandrels, and hence the blanks are gradually pressed u and around the proximate mandrels by t e action of the internal walls" of the-forming member, the flanged edges of the blank as it approaches and reaches the rear end of such member thus being turned into juxta-relation and disposed'in the longitudinal groove or channel in the mandrel.

In order to insure and maintain the positive gripping of the clamp levers against the blanks, as the latter are being moved along the machine and through. the forming de vices, there is affixed to the main frame directly beneath the path of travel of said levers, a horizontal rail 30 u on which the said lever rides and by which t 1e lever is held up against the can-body. (See Fig. 3

As each of the mandrels with its cylindrical blank passes fromthe forming member, a joint strip 31, is applied to the lipped edges of the blank. This feature of the invention is an important one. The I means hereinshown for forming and applying the strips is as follows; but it is to be understood that other meansto the same end may be employed without departing from my invention.

Supported upon posts 32 rlsing from the table, is ahorizontal bar 33 at one end of which is a hopper 34 in which are superposed rectly above the median line for an end shafts -36 sup chain 35.

30 scri the blanks B from which the joint strips are to be formed. This bar is supported dioft-he machine, and it is rovided with a longitudinal way Tess s rocket chain 35 which passes directly beneat 1 the hopper. The carrying .wheels for the sprocket chain are borne by sorted adjacent the respec tive vendsi-of t e plate, the rearward shaft being provided with a bevel gear which meshes-with aslmilargear 38 on a vertical shaft 391 The lower end of the latter shaft is geared with the main shaft by the coacting "wheels 4-0,"and hence the motion is transmitted from the main shaft to the chain. This chain is provided at regular intervais-with lugs 41 which, in their travel, take against the opposing ends of the successive lowermost strips in the hopper and move then1 along the bar 33. Supported on the 'bar, so as to leave an intervenrng another bar 42 extends a die rail 43.

space. is along the under side of'which The lowerside of this rail lies slightly above the plane of the bar 33 to afford a space for the passage of the strip,.

as the latter isimpelled by the sprocket Onthe respective sides of this rail are flanging wheels -14 which correspond in sha c with the wheels 15 previously debed, the wheels 44 being similarly arranged in two rows and being adapt-ed to act successively uponthe op osing edges of the blanks and thereby grac ually to turn such edges upon the flangesof the die rail to form corresponding longitudinal lips or flanges on the blanks. The wheels ll are carried by shafts 45 which are journaled in'the bars "33, -12. (See Figs. 19m 23, inclusive.)

At the rearward end of the bar 33 is an inclined chute 46d'own which the flanged strips descend endwise. These strips fall upon a supporting device WllIC-ll is arranged adjacent the rearward'end of the forming member, each strip being thereby supported horizontally inline with the recessed portion of the advancing mandrel, so that such portion will receive the strip and cause it to in terlock \viththe flanged edges of the canbodyj .The supportingdevice herein illustrated comprises two pairs of depending arms 47 loosely swungon a shaft 2: supported in arms 49 which overhang the path of travel of the mandrels. The lower ends of the arms 47 support the strip during the entry of the orward end of the strip into the channel of the mandrel. and that thereupon the jaws are opened to permitthe complete insertion of the' strip into the can-body as the strip bears against the 'abutment 51. The means to effect the opening of the jaws at the proper time comprises a vertical lever 53 pivoted to the'adjacent arm 49, and irovided at its upper end with two diverging links 54, one of which is connected with an n ward extension of one of the arms 47 and t 1e other is ,connected with the op osite arm at a point below the shaft 2:. T e lower end of the lever 53 is provided with a beveled shoe 55, which, when the jaws are closed, de)ends in the path of the edge of the mandrel. This shoe is so arranged that when the joint strip has been introduced into the channeled-end of the mandrel, the mandrel abuts against the shoe and thus forces the lever outward, the link connections with the jaw arms thereupon opening the latter, as indicated by the dotted lines in Fig. 9. The jaws are thus clear of the strip and the mandrel, and hence as the latter )rogressesthe strip is pushed wholly into t e channel. The end of the' mandrel then impinging against the pivoted body and strip, and thus effect a firm and stable bond between the edges of the canbody.

The hammer and its actuating devices are of such a construction that it imparts a uniform impactupon the body and strip during the continuous and uninterrupted travel 'of the mandrel. To this end, the hammer in .55 carry a pair of 'jaws 50 having horizontal its preferred form comprises a bar 56 correflanges, which, when the jaws are closed, spondinginlength with the can-body, and seafford a seat for the strip. (See Figs. 4 and cured to a slotted head 57. Slidingly fitted 9). Normallythe jaws are closed by grav-" in the slot 58 6f the head is a block 59 proity, and hence as the strip is discharged from vided with a circular orifice 60 in which is 60 the chute the strip passes-upon the undermounted an eccentric 6], keyed to a translying flanges. a I verse shaft 62. This shaft has its bearings Adjacent the outeror rearward-end of 'the in uprights 63 rising from the niiain frame, flanges is a depending'abutment piece 51. and carries at oneend a bevel gear wheel 64 Thispieceis' pivoted at its 11 er end to the wbichrneshes with a cor-res on wheel 65 65 adjacent arm- 49 and is hel normally in on a vertical shaft 66. T e latter shaft is ee passage of the shaft 62.

driven from the main shaft -2' by co-acting gear wheels 66 66 respectively. Keyed -on theshaft 62 adjacent one side of the head 1s a face cam 67, the cam groove of which re-' ceives a roller 68 carried by the head, and is of such form as to reciprocate the headhorizontally, that is, in the direction of movement of the mandrel and back again. Slidingly fitted to a horizontal guide way 69 in one of the uprights 63 is a head 70 which is rovided with a horizontal slot 71 for the Extending from'the top and bottom ofthe head 70 are two arms 72 respectively provided with vertical guide slots 73 which receive lateral roll.- ers 74 on the head 57. during the rotation of the shaft 62 the eccentric 61 imparts a. vertically reciprocating action to the block 59 and perforce to the head 57, the hammer on the latter thereupon striking the underlying can-body. 'This head is guided vertically by.its roller connections with the vertical slots 73 in the arms of the head 70, which latter head, being horizontally movable, is reci rocated transversely by the cam head 57 uring the operation of the latter by the cam 67- as above stated.

The resultant of the concurrent horizontaland vertical movements imparted to the hammer by the mechanism just described, is

an orbital movement which causes the ham-.

mer to act upon and move along for a short distance with the traveling can-body.

As the can-bodies are su'ccessivelyacted upon by the hammer they are carried by-the mandrels downwardly around the rearward wheel 20, and thence forwardly in a horizontal-plane; the seams of the can-bodies thus being on the underside of the forwardly travelin mandrels. Mounted below the path of the atter are novel fluxing andsoldermg de vices for the seams, which devices comprise :1 row ofgas burners 75 which first heat each of the seams as the can body advances: an oil device which then 1pplies oil, or any suitable fluiring' liquid, to t e seam, (a burner 76 being disposed below the oil device to heat 7. the contents thereof) a row of gas burners 77 the passage of a wick 84 which projects above the said bar into the path of the seams on the can-bodies and which 'wick' als-t; extends down It will be seen that VGSSG into the oil contents of the tank. The bar is held normally and yieldingly in the raised position by a suitably disposed spring or springs 85. Bythis construction it will be seen that lary attraction, and t at as the 'seamsfpass along in contact with the upper edge of the wlck, the latter will uniformly apply'the oil thereto.

The soldering device preferably comprises a long vessel 78 supported below the return path of travel of 'thecan-bodies. Extending within the vessel from end to end thereof is a bar 87 provided with a thin longitudinal slot. This bar may be a single integral member; or it may be conveniently composed of two slightly separated strips. The upper portion of this bar is tapered to enter into the space between the the can body, and hence the iquid sol er, as the can body travels along, passes by way of the slot, by capillary attraction, into such seam in a manner to effect a uniform application of the solder thereto.

Provision is had for the minute vertical andhorizontal adjustment of the vessel to insure the accurate disposition of the soldering bar in respect to the seams of the canbodies. To this end the vesselis-conveniently supported at itsends upon underlying cross bars 88 provided with upwardly projecting lugs 89' in which are fitted set screws 90 that take against the side members of the vessel. These bars in turn are carried'by and upon vertical set screws 91 extending through lower transverse bars 92 aflixed to depending-brackets 93 on the mainframe. By manipulating the screws 91 minute vertical adjustment ofthe bars and the soldering vessel thereon may be secured, and by mani ulating the set screws 90 the solder may be adjusted transversely on'the bars.

When the can-bodies leave the soldering device, they pass over an off-bearing sprocket chain 93, which is provided at regular intervals throughout its length with spurs 94 which, entering the longitudinal grooves or channels of the mandrels at points rearward of the seams, take against the opposing canbodies and strip them successively from their respective mandrels. The chain 93 passes around a sprocket wheel 95 on a transverse shaft 96 which is driven from the main shaft by the vertical shaft 97 and bevel gearing 98.
